Ultrasonic extraction technology method for response surface method-optimized purple perilla seed oil

Abstract

The invention discloses an ultrasonic extraction technology method for response surface method-optimized purple perilla seed oil. The ultrasonic extraction technology method comprises the following steps: grinding and sieving purple perilla seeds with a 60-mesh sieve, accurately weighing 3.0g of purple perilla seed powder and adding in a 50mL centrifugal tube, and respectively adding an extraction solvent and quartz sand; and by taking ethyl acetate as an extraction solvent, adding 0.02g of quartz sand, performing ultrasonic extraction for 50min at the ultrasonic temperature of 30.71 DEG C under ultrasonic power of 1150Hz according to the ratio of liquid to liquid being 1:7, to obtain purple perilla seed oil. By adopting purple perilla seeds as raw materials, the purple perilla seed oil is extracted under assistance of ultrasonic technology, the optimal purple perilla seed oil extraction technology can be obtained by selecting the optimal extraction solvent, ultrasonic temperature, material-liquid ratio, quartz sand addition quantity, ultrasonic time and ultrasonic power and then optimizing the ultrasonic time, temperature and the material-liquid ratio through adopting a response surface method, and the extraction rate of purple perilla seed oil under the technology is 36.77%. The ultrasonic extraction technology method is accurate and reliable in extraction conditions, beneficial to realization of industrial production, capable of quickening the development and utilization speed of purple perilla seed oil, thus having usage values.

Description

Technical field [0001] The invention belongs to the technical field of extraction of perilla seed oil, and in particular relates to an ultrasonic extraction process method of perilla seed oil optimized by response surface methodology. Background technique [0002] Perilla is one of the first 60 kinds of plant resources issued by the Ministry of Health of my country that are both food and medicine. The germplasm resources are very rich. Perilla seed oil has a high content of unsaturated fatty acids, especially rich in α-linolenic acid. Regular consumption can improve retinal reflexes, enhance eyesight, and at the same time reduce cholesterol content, lower blood lipids, anti-thrombotic, inhibit tumors, delay aging, etc. effect. In addition, perilla seed is a natural vegetable oil seed with the highest alpha-linolenic acid content found so far, and the content can be as high as 80%. It is a rare source of special edible oil and has a broad market prospect and application range. [...
